updated gitignore

Currently ignoring the `settings.py` file, all ropeproject files (this is a package used in st2 by me) and sample photos from media folder.
renamed settings.py

This was done for a deploy hook on an ftp server. In order not to overwrite the production `settings.py` file, it was renamed.
The instructions for using `settings.py` on staging will appear in the `README.md`.
delete all media files from staging
